Seats and Seat Controls
This section tells you about the seats in your vehicle and
how to adjust them.
CAUTION:
You can lose control of the vehicle if you try to
adjust the seat while the vehicle is moving. The
sudden movement could startle and confuse you,
or make you push a pedal when you don't want
to. Adjust the driver's seat only when the vehicle
is not moving.
Bucket and Bench Seats
If your vehicle has a bucket or bench seat, you can
adjust it with this lever at the front of the seat.
Slide the lever toward the outer seat support to unlock it.
Slide the seat to where you want it. Then, release the
lever and try to move the seat with your body to make
sure the seat is locked into place.

1-3 Head Restraints
Some seats have adjustable head restraints. Slide an
adjustable head restraint up or down so that the top of
the restraint is closest to the top of your ears. This
position reduces the chance of a neck injury in a crash.
Seatback Latches
The front of the full-width bench seat seatback folds
forward to let you reach the rear of the cab. Bucket seats
have outboard
-mounted levers to tilt the seatbacks
forward or rearward.
Your seatback will move back and forth freely unless
you come to a sudden stop
-- then it will lock into place.
If your vehicle is parked going down a fairly steep hill,
the seatback may not fold without some help from you.
To fold the seatback
forward, push the seatback
toward the rear of the
vehicle as you lift this latch.
The latch must be down for
the seat to work properly.
Bench Seat Shown
CAUTION:
If the seatback isn't locked, it could move
forward in a sudden stop or crash. That could
cause injury to the person sitting there. Always
press rearward on the seatback to be sure it
is locked.

Safety Belts: They're for Everyone
This part of the manual tells you how to use safety belts
properly. It also tells you some things you should not do
with safety belts.
CAUTION:
Don't let anyone ride where he or she can't wear
a safety belt properly. If you are in a crash and
you're not wearing a safety belt, your injuries
can be much worse. You can hit things inside the
vehicle or be ejected from it. You can be seriously
injured or killed. In the same crash, you might
not be if you are buckled up. Always fasten your
safety belt, and check that your passengers' belts
are fastened properly too.

CAUTION:
It is extremely dangerous to ride in a cargo area,
inside or outside of a vehicle. In a collision,
people riding in these areas are more likely to be
seriously injured or killed. Do not allow people to
ride in any area of your vehicle that is not
equipped with seats and safety belts. Be sure
everyone in your vehicle is in a seat and using a
safety belt properly.
If your vehicle has a safety
belt reminder light, a light
comes on as a reminder to
buckle up. (See ªSafety
Belt Reminder Lightº in
the Index.)If your vehicle has a safety belt reminder tone, a tone
comes on as a reminder to buckle up. See ªSafety Belt
Reminder Toneº in the Index.
In most states and Canadian provinces, the law says to
wear safety belts. Here's why: They work.
You never know if you'll be in a crash. If you do have a
crash, you don't know if it will be a bad one.
A few crashes are mild, and some crashes can be so
serious that even buckled up a person wouldn't survive.
But most crashes are in between. In many of them,
people who buckle up can survive and sometimes walk
away. Without belts they could have been badly hurt
or killed.
After more than 30 years of safety belts in vehicles,
the facts are clear. In most crashes buckling up does
matter ... a lot!
